Reasons for new version:Here the Mathematica(MM) packages QDensity, QCWave
[1, 2, 3] are updated for MM 9-10.3. Other quantum computer simulators using a
variety of languages, are described in [4]. The new QDENSITY, QCWAVE, BT-System packages include commands for entropy, Schmidt decomposition, partial
transposition, quantum discord, mutual information, and circuit diagrams, not
only for qubit systems but also for qutrit and hybrid qubit/qutrit systems.
The full array of new commands are provided in the Tutorial2014 notebook.
Compared to other Mathematica simulators, QDENSITY has a larger user and
application base, that is further enhanced by this update to qubit/qutrit systems. In the present upgrade, qubit, qutrit and hybrid (mixed qubit and qutrit) states and mixed qubit and qutrit gates are included (see BTSystems.m). Updated QC algorithms, a sample extension of teleportation to qutrits, examples
for random, Bell, GHZ, Werner and X-states are included.
